PILE FABRIC.

Application filed June 26, 1909.

T 0 all whom it may concern:

Be it known that I, GEORGE Cnossmno, a citizen of the United States, residing at \Vatertown, in the county of Middl-eseX and State of Massachusetts, have invented certain new and useful Improvements in File Fabric, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to woven pile fabrics, and has for its objects, first, to provide a very strong, durable and tightly woven fabric; second, a greatly increased binding capacity for supporting the pile tufts; third, economy in the material employed.

In the construction of my improved fab ric I form a practically independent upper ply by interweaving two sets of body warp threads and the upper plane weft threads, whereby by the combination of the interspersing binder warp threads in addition to the body warp threads a firm foundation and greatly increased support for the pile tufts is provided. The employment of two sets of upper body warp threads and inter weaving the same with the upper weft threads, allows said warp threads, as they lie so nearly straight, to be drawn very tightly, thus making the upper portion of the carpet very strong, firm and compact, and also as these threads, combined with the binder warp threads, serve to more completely fill the dent space they lie up against the sides of the pile tufts, to firmly support said tufts longitudinally, and by drawing and binding the body warp threads tightly the weft threads are compressed and the tufts are supported transversely thus causing the pile to stand stiff and straight giving the face of the carpet more spring and resiliency and increasing its effective wearing life. This method of constructing carpet, by interweaving the body warp and the upper weft threads to form a separate upper plane and interspersing the binder warp threads, applies to all carpet fabrics of the kind known as tapestry velvets, tapestry wiltons, and body Wilton carpets.

Vith these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1is a diagrammatic view illustrating a Specification of Letters Patent.

vertical longitudinal section of a portion of a pile fabric embodying my invention with the pile uncut. Fig. 2 represents the pile fabric with the upper plane woven as that in Fig. 1 with the pile threads cut, and showing one weftthread in the shed of the lower plane instead of two. Fig. 3-illustrates a modified construction with the pile loops uncut. Fig. 4tis a modification of the construction shown in Fig. 1, in which the binder threads are shown as being crossed between the adjacent upper plane weft threads in the same shed. V

In the accompanying drawings, 1 is the pile warp thread which is carried over the pile wire, (not shown), usually first in one direction and then .in the other as is customary to form loops of pile uponthe upper plane of the fabric. The loops may be uncut as shown in Figs. 1 and 3 for Brussels carpet fabrics or cut as shown in Fig. 2, for \Vilton, moquettc or Axminster carpet fabrics. This pile warp is bound into the upper plane of the fabric by the upper weft or filling threads 2 which extend transversely through the fabric over the pile warps, as shown.

The essential feature of my improved fab ric is the use of two sets of body threads 3 and 4: which are adapted to be interwoven in various Ways with the upper Weft threads 2 to form a firm and compact upper portion or layer of the carpet for the purpose of more securely binding and firmly supporting the upwardly extending pile threads 1.

In some cases, as illustrated in Figs. 1 and 2, both sets of the body warp threads are passed alternately over and under every other pair of Weft threads in the upper plane. In other cases, as illustrated in Fig. 3, the body Warp threads are passed alternately over and under every other one of the weft threads in said upper plane thereby drawing these transverse weft threads tightly together supporting the pile tufts between these threads, and also forming a most compact and firm construction. Then again, by laying these tightly drawn 1ongitudinal body threads, combined with the interspersed binder Warp threads, up against the sides of the pile tufts the same are also given a firm support in this direction.

The figuring pile threads 5 are of different colors, and when not used as pile threads are Woven into the body of the fabric to serve as the stuffer. These threads are used l in the weaving of pile fabric which is known as a five or six frame body \Vilton carpet.

The back of the fabric may be arranged to have one or more of the weft threads 6 in each shed of the lower plane of the fabric, one thread being illustrated in Fig. 2 in each shed, while two threads are shown in each shed in Figs. 1 and 3. The binder warp threads 7 and 8 serve to bind and secure the lower plane weft threads 6 to the back of the fabric, and the upper plane weft threads 2 together with the body warp and pile threads, to the face of the fabric. In other words, these binder threads firmly secure the face yarns and the back yarns tightly together with the dead yarn or stuffer between them. In addition to the above, these binder warp threads also serve to give an increased support to the sides of each pile tuft owing to the space occupied by their diameters between the body warp thread and the base of each tuft of pile formed in each reed dent.

It will be understood that the details of the weave of my improved fabric may be varied, if desired, and any preferred number of frames may be used in weaving the same without changing the construction of the fabric above described, the pile warps being disposed of in any usual or preferred manner.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A pile fabric comprising an upper and a lower weft plane, two sets of body warp threads interwoven over and under every other pair of weft threads in the upper plane, a pile forming figuring warp thread bound by each upper plane weft thread, a stutter, and binder threads engaging the weft threads in both planes to bind the whole together and also to cooperate with said body warp threads to form a lateral support for the pile tufts.

2. A pile fabric comprising an upper and a lower weft plane, two sets of body warp threads interwoven with said upper plane weft threads, a stuffer, a pile forming warp thread bound by each upper plane weft threads, and a binder warp thread engaging .tWo weft threads in the upper plane and one weft thread in the lower plane in each shed whereby the threads in both planes are bound together, said binder thread also acting in conjunction with the body warp threads to compress and support the pile tufts transversely.

3. A pile fabric comprising an upper and a lower weft plane, two sets of body warp threads interwoven with said upper plane weft threads only, a stuffer, pile forming warp threads bound by said upper plane weft threads, binder threads set in each course among said body warp and pile threads and having the same point of intersection as the body warp threads, said binder threads arranged to engage the weft threads in both planes to bind the whole together.

4. A pile fabric having binder threads, pile threads and a body warp thread, the latter being arranged in two sets or leaves to engage the weft threads in the upper plane only, said body warp being distributed among the pile threads and the binding threads, said binding threads being arranged to bind both the upper and lower weft planes together and also to cooperate with said body warp threads to form a lateral compressive bind adapted to act on both sides of each tuft or loop of pile formed between them to firmly support the pile tufts.

In testimony whereof I afiiX my signature in presence of two witnesses.

GEORGE CROSSLAND.
